UNITED STATES PATENT OFFICE.

EDWIN ALLEN, OF SOUTH VVINDIIAM, CONNECTICUT.

IMPROVED VENEER-POLISHER.

Specification forming part of Letters Patent No. 11,107, dated June 20, 1854.

.T0 all whom it may concern.-

Be it known that I, EDWIN ALLEN, of South Windham, in the county of Windham and State of Connecticut, have invented a new and improved machine for polishing veneered work and all kinds of wood which is required to be polished; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part ot this specification, in which-M Figure lisa side elevation of my improved machine. Fig. 2 is a longitudinal vertical section of the same, the plane of section being through the center.

Similar letters ot' reference indicate corresponding parts in the two figures.

The nature of my invention consists in the employment or use ot' a smoothing-belt and elastic pressure cylinder, constructed, arranged, and operating as will be presently shown. l

To enable others skilled in the art to make and use my invention, I will proceed toY describe its construction and operation.

A, Fig. 2, represents a horizontal board or bed-piece placed between two sills or side pieces B B, and C is a carriage placed upon the board or bed A.

D D are two rollers, one being placedat each end ot the board or bed A.

E is a belt, which passes around the rollers D D,the belt being attached to the under side ot the carriage C.

F is a horizontal frame, which is secured to uprights d, which are attached to or spring from the sills B B.

G G are rollers, one being placed at each end ot the frame F.

H is a roller placed at the upper part of adjustable uprights b, one ot' which is shown in both figures. y

I is a belt constructed of any proper material. This belt I passes around the rollers G G H, and may be tightened, when necessary, by raising the uprights b, these up-l rights being secured to the trame F by set screws c, one of which is shown in Fig. 1. The out-er surface of the belt I is covered with sand, emery, or a like substance.

J J are rollers secured in the frame F, and having between them a cylinder K, constructed of india-rubber cloth, and nearlytilled with water. This cylinder K rests upon the inner surface of the belt, as shown clearly in Fig. 2, and has no bearings, the cylinder being kept properly in place by the rollers J J. Cross-belts d cl pass around the rollers J J G G, as shown in Fig. 2 and by dotted lines in Fig. l.

Motion is given the several working parts by means of a belt e, which passes around a pulley L on one of the rollers D, (see Fig. l.) the belt e also passing around a pulley M on the outer side of one of the sills B. (See Fig. 1.) A belt f passes around a larger pulley N on the same axis as the pulley M and also around a pulley O on the end of one of the rollers G.

Operation: The plank, board, or other article to be smoothed or polished (represented by P) is placed upon the carriage C, and mo` tion is given the roller D, to which the pulley L is attached in any proper manuel'. The carriage C, and consequently the plank or board P, is moved underneath the belt I, the cylinder K causing by its weight the belt I to bear upon the board or plank P, and as the cylinder K is somewhat elastic, not being entirely iilled with water and having no axis, it will accommodate itself to any inequalities or unevenness of the board or plank.

The arrows in Fig. 2 show the direction in which the carriage, cylinders, and rollers move. Y

By the above invention the board or plank will be perfectly smoothed or polished.

The machine is simple, not liable to get out of repair, and is economical to manufacture.

I do not` claim the belt I separately, for belts or their equivalents have been previously used for similar purposes; but

What I claim as new, and desire to secure by Letters Patent, is

The combination of the belt I and pressurecylinderK, constructed, arranged, and operating in the manner and for the purpose substantially as set forth.

t EDW'IN ALLEN.
